2015 GMC Sierra Best Buy Review

IT’S A BEST BUY BECAUSE:

Like the nearly identical Chevrolet Silverado, the Sierra is a capable, refined truck offering an impressive array of features.

BUT…

Ride comfort and interior ergonomics, while good, are a step behind those of the Ram 1500.

WORTH NOTING:

Full-time 4WD (rather than less-convenient part-time) is offered on most models. The available 6.2-liter V8 offers class-leading power.

WHAT IS IT?

GMC’s Sierra is a near clone of the Chevrolet Silverado, though it’s differentiated with unique styling and a slightly different equipment mix. Regular cab, extended cab, and crew cab body styles are offered, as are V6 and V8 engines and full-time 4WD.

WHAT’S NEW?

After its redesign last year, Sierra gets a number of updates for 2015. The most notable are an 8-speed automatic transmission for the 6.2-liter V8 and magnetic ride control adaptive suspension for the line-topping Sierra Denali model. Also new are available trailering mirrors with LED back-up lamps, available spray-on bedliner, updated IntelliLink infotainment system with Text Messaging Alerts and Siri Eyes Free, and available 4G LTE Internet connectivity with a built-in WiFi hotspot.

FUEL ECONOMY

In a similar Silverado 2WD crew cab equipped with the 5.3-liter V8, we averaged 18.6 mpg in a mix of city/highway driving. That compares favorably with the EPA combined rating of 19 mpg. (The EPA city rating is 16, the highway rating 23.) The standard 4.3-liter V6 is rated at 18 city/24 highway, while the 6.2 is rated at 15 city/21 highway. All engines can use regular-grade fuel, though premium is recommended for the 6.2 for best performance.

VALUE IN CLASS

The GMC Sierra stacks up well against class rivals, and—like its Chevrolet Silverado sibling—offers strong, refined engines, good on-road behavior, plenty of handy in-cabin storage, and an impressively quiet driving environment; top-line models such as the Denali add a healthy dose of luxury to the mix. Sierra lags the Ram 1500 in ride quality, but it’s a strong competitor in this class.
